In Celtic wisdom the sacred is as present on earth as it is in heaven, as immanent as it is transcendent, as human as it is divine, as physical as it is spiritual. The sacred can be breathed in, tasted, touched, heard, and seen as much in the body of the earth and the body of another living being as in the body of religion. It is the true essence of all life.
It is not difficult to understand why music often touches us so deeply. Music is the key to the power within -- a bridge of sorts -- and there is an infinite variety of music suitable to individual tastes and preferences to lead in this inward search. Composers are often aware of the power of the music that comes from within them and have from time to time spoken of it ... Brahms, being deeply aware of the source of his creative gift, stated that his creative power was released in the moment of his realization of his oneness with the Creator.
